# 天灾导弹防御塔 - C# 实现计划
本文档包含构建“天灾导弹防御塔”所需的全部C#类的源代码。这些代码基于 `Rimatomics` 的跨地图打击框架，并与我们自己的 `Projectile_CruiseMissile` 弹头相结合。
---
## 1. 建筑类: `Building_CatastropheMissileSilo.cs`
**路径**: `Source/ArachnaeSwarm/Buildings/Building_CatastropheMissileSilo.cs`
**功能**: 这是导弹发射井的建筑本体，负责处理玩家的瞄准指令。它几乎是 `Building_Railgun` 的翻版，但进行了一些重命名和命名空间调整。
```csharp
using System;
using System.Collections.Generic;
using System.Linq;
using RimWorld;
using RimWorld.Planet;
using UnityEngine;
using Verse;
using Verse.Sound;
namespace ArachnaeSwarm
{
[StaticConstructorOnStartup]
public class Building_CatastropheMissileSilo : Building
{
public CompPowerTrader powerComp;
public CompRefuelable refuelableComp;
public Verb_LaunchCatastropheMissile verb;
private GlobalTargetInfo longTargetInt;
private List<Building_CatastropheMissileSilo> selectedSilos;
public static readonly Texture2D FireMissionTex = ContentFinder<Texture2D>.Get("UI/Commands/Attack", true);
public override void SpawnSetup(Map map, bool respawningAfterLoad)
{
base.SpawnSetup(map, respawningAfterLoad);
this.powerComp = base.GetComp<CompPowerTrader>();
this.refuelableComp = base.GetComp<CompRefuelable>();
// This is a placeholder, verb will be initialized from the weapon ThingDef
this.verb = (Verb_LaunchCatastropheMissile)Activator.CreateInstance(typeof(Verb_LaunchCatastropheMissile));
this.verb.caster = this;
}
public override void ExposeData()
{
base.ExposeData();
Scribe_TargetInfo.Look(ref this.longTargetInt, "longTargetInt");
}
public override IEnumerable<Gizmo> GetGizmos()
{
foreach (Gizmo c in base.GetGizmos())
{
yield return c;
}
Command_Action launch = new Command_Action
{
defaultLabel = "CommandFireMission".Translate(),
defaultDesc = "CommandFireMissionDesc".Translate(),
icon = FireMissionTex,
action = new Action(this.StartChoosingDestination)
};
if (!CanFire())
{
launch.Disable("CannotFire".Translate() + ": " + GetDisabledReason());
}
yield return launch;
}
private bool CanFire()
{
return powerComp.PowerOn && refuelableComp.HasFuel;
}
private string GetDisabledReason()
{
if (!powerComp.PowerOn) return "NoPower".Translate().CapitalizeFirst();
if (!refuelableComp.HasFuel) return "NoFuel".Translate().CapitalizeFirst();
return "Unknown";
}
private void StartChoosingDestination()
{

CameraJumper.TryJump(CameraJumper.GetWorldTarget(this), CameraJumper.MovementMode.Pan);
Find.WorldSelector.ClearSelection();
Find.WorldTargeter.BeginTargeting(
new Func<GlobalTargetInfo, bool>(this.ChoseWorldTarget),
true, // Can target self
FireMissionTex,
true,
() => GenDraw.DrawWorldRadiusRing(this.Map.Tile, this.MaxWorldRange),
(GlobalTargetInfo t) => "Select target",
null, null, true);
}
private bool ChoseWorldTarget(GlobalTargetInfo target)
{
if (!target.IsValid)
{
Messages.Message("MessageTargetInvalid".Translate(), MessageTypeDefOf.RejectInput, true);
return false;
}
int distance = Find.WorldGrid.TraversalDistanceBetween(this.Map.Tile, target.Tile, true, int.MaxValue);
if (distance > this.MaxWorldRange)
{
Messages.Message("MessageTargetBeyondMaximumRange".Translate(), this, MessageTypeDefOf.RejectInput, true);
return false;
}
MapParent mapParent = target.WorldObject as MapParent;
if (mapParent != null && mapParent.HasMap)
{
Map targetMap = mapParent.Map;
var originalMap = base.Map;
Action onFinished = () => {
if (Current.Game.CurrentMap != originalMap) Current.Game.CurrentMap = originalMap;
};
Current.Game.CurrentMap = targetMap;

}
return true;
}
}
public void FireMission(int tile, LocalTargetInfo targ, int mapId)
{
if (!targ.IsValid)
{
this.longTargetInt = GlobalTargetInfo.Invalid;
return;
}
Map targetMap = (mapId != -1) ? Find.Maps.FirstOrDefault(m => m.uniqueID == mapId) : null;
this.longTargetInt = new GlobalTargetInfo(targ.Cell, targetMap);
this.verb.verbProps.defaultProjectile.GetModExtension<CruiseMissileProperties>(); // Ensure verb has properties.
this.verb.TryStartCastOn(this.longTargetInt);
}
public int MaxWorldRange => 99999; // Effectively global range
public GlobalTargetInfo LongTarget => longTargetInt;
}
}
```

## 2. 动作类: `Verb_LaunchCatastropheMissile.cs`
**路径**: `Source/ArachnaeSwarm/Verbs/Verb_LaunchCatastropheMissile.cs`
**功能**: 定义发射动作。它会创建 `WorldObject_CatastropheMissile` 并将其发射到世界地图。
```csharp
using RimWorld;
using RimWorld.Planet;
using UnityEngine;
using Verse;
namespace ArachnaeSwarm
{
public class Verb_LaunchCatastropheMissile : Verb_Shoot
{
public override bool CanHitTargetFrom(IntVec3 root, LocalTargetInfo targ)
{
return true; // Always true for world-map targeting
}
protected override bool TryCastShot()
{
Building_CatastropheMissileSilo silo = this.caster as Building_CatastropheMissileSilo;
if (silo == null || !silo.LongTarget.IsValid) return false;
WorldObject_CatastropheMissile missile = (WorldObject_CatastropheMissile)WorldObjectMaker.MakeWorldObject(
DefDatabase<WorldObjectDef>.GetNamed("CatastropheMissile_Flying")
);
missile.Tile = silo.Map.Tile;
missile.destinationTile = silo.LongTarget.Tile;
missile.destinationCell = silo.LongTarget.Cell;
missile.Projectile = this.verbProps.defaultProjectile;
Find.WorldObjects.Add(missile);
// Consume fuel
silo.refuelableComp.ConsumeFuel(silo.refuelableComp.Props.fuelConsumptionRate);
// Visual/Sound effects at launch site
MoteMaker.MakeStaticMote(silo.TrueCenter(), silo.Map, ThingDefOf.Mote_ExplosionFlash, 10f);
SoundDefOf.RocketLaunch.PlayOneShot(new TargetInfo(silo.Position, silo.Map));
return true;
}
}
}
```
---
## 3. 飞行物类: `WorldObject_CatastropheMissile.cs`
**路径**: `Source/ArachnaeSwarm/World/WorldObject_CatastropheMissile.cs`
**功能**: 模拟导弹在世界地图上的飞行，并在抵达时生成 `Projectile_CruiseMissile`。
```csharp
using RimWorld.Planet;
using UnityEngine;
using Verse;
using RimWorld;
namespace ArachnaeSwarm
{
public class WorldObject_CatastropheMissile : WorldObject
{
public int destinationTile = -1;
public IntVec3 destinationCell = IntVec3.Invalid;
public ThingDef Projectile;
private int initialTile = -1;
private float traveledPct;
private const float TravelSpeed = 0.0002f; // Faster than sabot
public override void ExposeData()
{
base.ExposeData();
Scribe_Values.Look(ref destinationTile, "destinationTile", 0);
Scribe_Values.Look(ref destinationCell, "destinationCell");
Scribe_Defs.Look(ref Projectile, "Projectile");
Scribe_Values.Look(ref initialTile, "initialTile", 0);
Scribe_Values.Look(ref traveledPct, "traveledPct", 0f);
}
public override void PostAdd()
{
base.PostAdd();
this.initialTile = this.Tile;
}
private Vector3 StartPos => Find.WorldGrid.GetTileCenter(this.initialTile);
private Vector3 EndPos => Find.WorldGrid.GetTileCenter(this.destinationTile);
public override Vector3 DrawPos => Vector3.Slerp(StartPos, EndPos, traveledPct);
public override void Tick()
{
base.Tick();
traveledPct += TravelSpeed / GenMath.SphericalDistance(StartPos.normalized, EndPos.normalized);
if (traveledPct >= 1f)
{
Arrived();
}
}
private void Arrived()
{
Map targetMap = Current.Game.FindMap(this.destinationTile);
if (targetMap != null)
{
// Target is a loaded map, spawn the projectile to hit it
IntVec3 entryCell = Find.WorldGrid.GetRotatedPos(new IntVec2(0, 1), targetMap.info.parent.Rotation).ToIntVec3() * (targetMap.Size.x / 2);
entryCell.y = 0;
entryCell.z += targetMap.Size.z / 2;
Projectile_CruiseMissile missile = (Projectile_CruiseMissile)GenSpawn.Spawn(this.Projectile, entryCell, targetMap, WipeMode.Vanish);
missile.Launch(this, this.destinationCell, this.destinationCell, ProjectileHitFlags.IntendedTarget);
}
else
{
// Target is not a loaded map (e.g., caravan, site), do direct damage
GenExplosion.DoExplosion(
this.destinationCell,
null, // No map
this.Projectile.GetModExtension<CruiseMissileProperties>()?.customExplosionRadius ?? 5f,
this.Projectile.GetModExtension<CruiseMissileProperties>()?.customDamageDef ?? DamageDefOf.Bomb,
null, // Launcher
this.Projectile.GetModExtension<CruiseMissileProperties>()?.customDamageAmount ?? 50
);
}
Find.WorldObjects.Remove(this);
}
}
}

# Rimatomics 电磁炮战略打击系统技术文档
## 1. 引言
本文档旨在详细解析 Rimatomics Mod 中的电磁炮（Railgun）远程战略打击系统的实现机制。该系统允许玩家对世界地图上的任意（已加载的）地图进行精确的火力投送，是游戏中一种强大的后期战略武器。
我们将通过分析其三个核心 C# 类：`Building_Railgun`、`Verb_Railgun` 和 `WorldObject_Sabot`，来深入理解其功能、设计模式以及类之间的交互。
## 2. 核心组件概览
整个系统由三个主要部分协同工作，各司其职：
* **`Building_Railgun`**: 炮塔建筑本身，是整个系统的用户交互入口和武器平台。它负责处理玩家的瞄准指令，管理武器的属性（如射程、精度），并发起射击流程。
* **`Verb_Railgun`**: 定义了电磁炮的“射击”这一具体动作。它能够智能区分常规的本地射击和需要跨地图飞行的远程打击，并根据不同模式执行相应的逻辑。
* **`WorldObject_Sabot`**: 一个在世界地图上存在的临时对象，用于模拟炮弹在飞向目标过程中的状态。它负责处理跨地图飞行、轨迹计算，并在抵达目标后触发最终的命中效果。
## 3. 类详解
### 3.1 `Building_Railgun`
`Building_Railgun` 是电磁炮塔的建筑类，继承自 `Building_EnergyWeapon`。它是玩家能直接看到并与之交互的实体。
#### 功能概述
此类作为系统的交互枢纽，主要负责以下功能：
* **提供玩家操作界面**：通过 Gizmo（操作按钮）让玩家启动“火控任务”。
* **处理目标选择流程**：引导玩家从世界地图选择目标区域，再到目标地图内选择精确弹着点。
* **管理武器状态与属性**：存储远程目标信息，并根据已安装的升级动态计算射程、散布等属性。
* **发起射击指令**：在获取有效目标后，命令自身的武器组件（Verb）开火。

#### 关键方法和属性详解
* **`GetGizmos()`**: 为炮塔添加“火控任务” (Fire Mission) 按钮，这是远程打击流程的起点。如果炮塔被屋顶遮挡，该按钮会被禁用。
* **`StartChoosingDestination()`**: 响应按钮点击，将视角切换到世界地图，并启动一个带射程圈的目标选择器，让玩家选择目标地块。它支持多炮塔同时选择。
* **`ChoseWorldTarget(GlobalTargetInfo target)`**: 当玩家在世界地图上选择目标后的回调函数。它会进行一系列合法性验证（如射程、是否为当前地图等），如果通过，则将视角切换到目标地图，让玩家选择精确落点。
* **`FireMission(int tile, LocalTargetInfo targ, int map)`**: 这是目标选择的最后一步。它将最终的、精确的目标信息（包含地块ID和地图内坐标）存入 `longTargetInt` 变量，并立即尝试触发射击 (`TryStartShootSomething()`)。该方法支持多人游戏同步。
* **`WorldRange` (get)**: 一个计算属性，返回炮塔在世界地图上的最大射程。基础射程定义在XML中，并会受到 `TargetingChip` 和 `MEPS` 等升级的加成。
* **`spread` (get)**: 计算属性，返回炮弹的散布半径。`TargetingChip` 升级可以减小此值，提高精度。
* **`CanFireWhileRoofed()`**: 重写方法，规定在执行远程打击 (`longTargetInt` 有效) 时，炮塔不能处于屋顶之下。
### 3.2 `Verb_Railgun`
`Verb_Railgun` 继承自 `Verb_RimatomicsVerb`，它定义了电磁炮武器的“射击”这个核心动作。它不处理玩家交互，只负责执行射击逻辑。
#### 功能概述
这个类的主要职责是根据炮塔当前的目标状态（本地目标 vs 远程目标），决定执行哪种射击模式。
* **动态炮弹选择**: 根据 `CompChangeableProjectile` 组件的状态，决定是发射已装填的特殊炮弹还是默认炮弹。
* **射击模式分发**: 检查是否存在远程目标 (`longTarget`)，如果存在，则执行“火控任务”流程；否则，执行标准的本地射击。
* **远程打击发起**: 在“火控任务”模式下，负责创建并初始化 `WorldObject_Sabot`，将其发射到世界地图。
* **本地打击后效**: 为本地射击附加额外的效果，如能量消耗、数据收集和屏幕震动。

```
#### 关键方法和属性详解
* **`Projectile` (get)**: 这是一个动态属性，用于获取当前应该发射的炮弹类型。它会优先返回 `CompChangeableProjectile` 中已装填的炮弹，如果未装填，则返回在 XML 中定义的默认炮弹。
* **`CanHitTargetFrom(...)`**: 重写了基类方法。当炮塔被赋予了一个远程目标 (`longTarget.IsValid`) 时，该方法直接返回 `true`，绕过了所有常规的射程和视线检查，确保远程打击流程可以启动。
* **`TryCastShot()`**: 这是射击动作的入口点。它的核心逻辑是检查 `railgun.longTarget` 是否有效。
* 如果**有效**，说明是远程打击任务，它便调用 `TryCastFireMission()`。
* 如果**无效**，说明是常规的本地瞄准，它就调用基类的 `base.TryCastShot()` 来发射普通炮弹，并附加一系列开火后效。
* **`TryCastFireMission()`**: 这是发起远程打击的核心。它不直接生成命中目标的炮弹，而是：
1. 创建一个 `WorldObject_Sabot` 实例。
2. 将目标地块、精确坐标、炮弹类型、散布等关键信息从 `Building_Railgun` 传递给 `sabot` 对象。
3. 将 `sabot` 添加到世界对象管理器 (`Find.WorldObjects.Add(sabot)`)，让其开始在世界地图上“飞行”。
4. 触发炮口闪光、能量消耗、屏幕震动等本地开火效果。
5. 生成一个飞向地图外的“虚拟”炮弹，仅用于视觉表现，它不会造成任何伤害。
### 3.3 `WorldObject_Sabot`
`WorldObject_Sabot` 继承自 `WorldObject`，是远程打击流程中的“飞行”阶段的执行者。它是一个临时的、在世界地图上存在的实体，模拟了炮弹从发射点到目标点的飞行过程。
#### 功能概述
此类完全独立于发射它的炮塔，其核心职责是在世界地图上完成一段旅程，并在抵达终点时触发命中效果。
* **飞行轨迹模拟**: 通过 `DrawPos` 属性和 `Tick` 方法，平滑地计算并更新自身在世界地图上的位置，实现飞行-动画效果。
* **状态持久化**: 通过 `ExposeData` 方法保存所有关键信息（如起点、终点、飞行进度、炮弹类型），确保在游戏存读档后飞行可以继续。
* **命中触发**: 在飞行到达终点后，`Arrived` 方法负责在目标地图上生成真正的 `Projectile`（炮弹），并让其从地图边缘发射，命中最终的精确弹着点。
* **自我销毁**: 完成命中逻辑后，将自身从世界对象管理器中移除。
* **Mod兼容性**: 能够识别并处理 "Save Our Ship 2" Mod 中的轨道飞船，实现地对空、空对地和空对空打击。

#### 关键方法和属性详解
* **`Start` / `End` (get)**: 这两个属性负责计算飞行的起点和终点坐标。它们通过检查 `HarmonyPatches.SoS` 来判断是否加载了 "Save Our Ship 2" Mod，如果加载了，则会尝试获取轨道上飞船的位置作为起点/终点，从而实现与该Mod的无缝兼容。
* **`DrawPos` (get)**: 重写属性，用于在世界地图上渲染该对象。它使用 `Vector3.Slerp`（球面线性插值）在起点和终点之间进行插值，根据 `traveledPct`（已飞行百分比）计算出当前帧应该在的位置，从而形成一条平滑的弧形飞行轨迹。
* **`Tick()`**: 游戏引擎为每个世界对象调用的更新方法。它在每一帧增加 `traveledPct` 来推进飞行进度。当 `traveledPct` 达到1时，调用 `Arrived()`。
* **`Arrived()`**: 这是飞行结束、触发命中的核心方法。它首先检查目标地块是否存在一个已加载的地图。如果存在，它会在该地图的边缘生成 `Projectile` 实体，并根据 `spread`（散布）在目标点附近随机一个最终落点，然后调用炮弹的 `Launch()` 方法完成最后的攻击。无论地图是否存在，它最终都会将自己从世界上移除。
* **`ExposeData()`**: 保证了该飞行物体的所有状态（起点、终点、进度、炮弹类型等）都能被正确地保存和加载。
## 4. 系统工作流程
现在我们将三个核心组件联系起来，详细描述从玩家点击按钮到炮弹命中的完整工作流程。

```
### 4.2 步骤分解
1. **启动与目标选择 (玩家 -> `Building_Railgun`)**
* 玩家选中一门或多门 `Building_Railgun` 并点击其 "Fire Mission" Gizmo。
* `GetGizmos` 触发 `StartChoosingDestination` 方法，视角切换至世界地图，并显示最大射程圈。
* 玩家在世界地图上选择一个目标地块。
* `ChoseWorldTarget` 方法被回调。在通过一系列验证后，视角切换到目标地图。
* 玩家在目标地图上选择一个精确的弹着点。
2. **下达指令 (`Building_Railgun` -> `Verb_Railgun`)**
* 当精确弹着点被选定后，`ChoseWorldTarget` 方法会为所有被选中的炮塔调用 `FireMission` 方法。
* `FireMission` 将包含地块和坐标的 `GlobalTargetInfo` 存入炮塔的 `longTarget` 变量中。
* `FireMission` 随即调用 `TryStartShootSomething()`，这会启动炮塔的射击冷却计时器，并最终触发其Verb组件。
3. **发射与创建飞行物 (`Verb_Railgun` -> `WorldObject_Sabot`)**
* 炮塔的 `Verb_Railgun` 组件的 `TryCastShot` 方法被调用。
* `TryCastShot` 检测到 `longTarget` 是有效的，因此它不会执行常规射击，而是调用 `TryCastFireMission`。
* `TryCastFireMission` 创建一个 `WorldObject_Sabot` 的实例，并将目标信息、炮弹定义、散布等关键数据从 `Building_Railgun` 复制到这个新实例中。
* `WorldObject_Sabot` 被添加到 `Find.WorldObjects` 管理器中，正式开始其生命周期。
* 同时，`Verb_Railgun` 在本地触发开火的视觉和听觉效果。
4. **跨地图飞行 (`WorldObject_Sabot`)**
* `WorldObject_Sabot` 作为一个独立的世界对象，其 `Tick` 方法被游戏引擎在每一帧调用。
* `Tick` 方法不断更新 `traveledPct` 属性，模拟飞行进度。
* 其 `DrawPos` 属性根据 `traveledPct` 在世界地图上平滑地渲染出飞行轨迹。
5. **抵达与命中 (`WorldObject_Sabot` -> `Projectile`)**
* 当 `traveledPct` 达到100%时，`Arrived` 方法被调用。
* `Arrived` 检查目标地块的地图是否已加载。
* 如果地图已加载，它会在地图边缘 `GenSpawn.Spawn` 一个真正的 `Projectile`（最终炮弹）。
* 根据从 `Building_Railgun` 继承来的 `spread` 值，在玩家指定的精确落点附近随机一个最终弹着点。
* 调用 `Projectile.Launch()`，使其从地图边缘飞向并命中最终弹着点，产生爆炸和伤害。
* 最后，`WorldObject_Sabot` 调用 `Find.WorldObjects.Remove(this)` 将自己从世界上移除，完成其使命。
## 5. 总结
Rimatomics的电磁炮系统是一个设计精良的远程打击模块。它通过将**交互(Building)**、**动作(Verb)**和**飞行(WorldObject)**三个阶段清晰地分离到不同的类中，实现了高度的内聚和低耦合。这种设计不仅使得代码逻辑清晰、易于维护，还通过 `WorldObject` 机制优雅地解决了跨地图状态同步和持久化的问题，并为兼容其他Mod（如Save Our Ship 2）留出了接口。
